Urinary Tract Infection (UTI)
in Adults Mind Map: An Overview

What is Urinary Tract Infection
(UTI)?

It is an infection that occurs in
the urinary tract; often caused by bacteria such as Escherichia coli.

UTI Epidemiology

About 60% of women suffer a UTI in
their life. Symptomatic infection is more common in young women after the onset
of sexual activity (20 to 50 years old).
And it is uncommon in males < 50 years old. The incidence of urinary
tract infection increases in both sexes over 50 years, but the female: male
ratio decreases due to the increased frequency of prostate disease in males.

Why do women have a
greater incidence of urinary tract infections than men?

Women's urethras
are shorter, which makes it easier for bacteria to make it's way into
the body and cause infections. Women's urethras are also located closer
to their rectums which makes it easier for bacteria to travel to the
urethra and gain entry into the body. In addition, urine is stagnant in
women; forming a good medium for growth of microorganisms. This is more
significant with pregnant women due to the weak peristaltic movement of
urethra in pregnancy, which means more urine stagnation.

Lab Tests for UTI, including:

1-Urinalysis, which is done through dipstick tests or microscopic
examination of urine. Tests' results and indications are stated in the map.

2-Urine Culture & Sensitivity, which is a quantitative test that is not
recommended to diagnose or verify uncomplicated UTI.

Special Conditions

Asymptomatic Bacteruria (ASB)

A condition in which 2 consecutive
urine cultures growing more than 100,000 colony-forming units (CFU) of bacteria
/ ml urine in a patient lacking symptoms of a UTI. It is common in elderly,
pregnant women, diabetic patients, and cathetarized patients. To know how to
manage Asymptomatic Bacteruria, see the map above. Just click the image to
